Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

Full-fuel-cycle GHG emissions estimates for reformulated gasoline pathways by LCA study. Nominal value of 70 g CO 2 /MJ for combustion emissions is applied evenly across all studies. He found that the variation in oil sands GHG estimates is due to a variety of causes. Credit: ACS, Brandt 2012. Click to enlarge.

Researchers Suggest That Although CCS and Other Technologies Could Reduce Oil Sands GHG Emissions to Near Zero, That Strategy May Not Make Sense

Green Car Congress

Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., The source material is neither oil nor tar but bitumen, but is most generally described as an example of ultraheavy oil.”.

Transcanada restarts Keystone oil sands pipeline operations

Green Car Congress

TransCanada Corporation said that its 590,000 barrel-per-day (bpd) capacity Keystone Pipeline system resumed transporting oil sands crude on Sunday, 5 June, after a shutdown 29 May following an above-ground spill at a pump station in Kansas involving less than 10 barrels of oil. The tar sands are estimated (e.g.,

MIT/RAND Study Concludes Three Types of Alternative Jet Fuel May Be Available in Commercial Quantities Over the Next Decade

Green Car Congress

Normalized well-to-wake GHG emissions for low-, baseline- and high-emission cases for jet fuel pathways under different land use change scenarios. The focus of the work was on alternative jet fuels that could be available commercially in the next decade using primarily North American resources. From Hileman et al.
